Publicerad 2012-12-05

Place of action
Electronic Defence Systems, a business area of Saab, is one of the world’s premier suppliers of solutions for surveillance, avionics and systems to detect, locate and protect against threat.
At our site in Jönköping we are developing computer based systems and components for the next generation of aircraft from the world-leading aircraft manufacturers. Our group is working with specification, development and verification of software for utility and mission computers, control computers, hydraulic actuators, electric motors and motor controllers.

Your future challenge
The Master’s thesis concerns theoretic and practical studies of magnetic effects on electric components and systems.
The task for this Master’s thesis is to quantify the influence caused by these interfering components;
• What is the core component that causes the interference
• Quantify what disturbance will cause failure
• What distance is can be considered as ‘safe zone’, quantify the relation between interference and distance
• What shielding effect has the aluminium that is used for the housing today, wall thickness influence
• Are there any additives/aluminium alloys that can be used for housing material to improve the system
If the true effects and limits of this effect would be fully known and understood, the possibility to optimize the design in terms of weight and packaging would be significantly improved
Your job will include planning, specification and documentation.
